RAILWAY-TRACK CAR.

Speccaton of Letters Patent.

Patented July 5, 1910.

Application filed September 29, 1909. Serial No. 520,070.

To all whom it may concern:

Be it known that I, MERRILL L. JENKINS, a citizen of the United States, residing at I-Iarvey, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Railway-Track Cars, of which the following is a specification.

My present invention relates primarily to railway motor velocipedes, and has special reference t-.o velocipedes driven by explosive engines.

The principal objects of my invention are the provision of an improved form of construction of vehicles of the character referred to and one which will be stronger and less likely to fail or get out of order in service than others known to me; to provide improved frame work for such cars, by the use of which I can attain a very much greater degree of strength without appreciable, if any, increase in weight.

A further object of my invention is the provision of an improved form of driving connection between the motor and the driving wheel, embodying a positive driving connection between the motor shaft and the large driving gear or sprocket and a yieldingly resistant connection interposed betw'een said sprocket and the driving wheel, whereby strain or shock, such as occurs at the instant explosion takes place in the motor, or as might be incident in the event of accident, or jarring in passing over frogs or switches and all other shocks which impose great tension upon the driving chain, may be compensated for.

Still another object of my invention is the provision of an improved arrangement of seats and controlling levers whereby three or more people may be carried on the car and whereby the car may be more conveniently used and manipulated.

In the attainment of the foregoing objects, I have provided the construction illustrated in the accompanying drawings wherein- Figure 1 is a side elevation of a car embodylng my improvements;

Figure 2 is a plan view of the car illustrated in Figure 1;

Figure is an end view' of a portion of said car;

Figure l is an elevation partly in section of an improved form of sprocket driving mechanism used on the driving wheel;

Figure 5 is a sectional View taken on the line V-V of Figure 4;

Figure 6 is a perspective view, illustrative of another form of car embodying my inventions.

Referring now more particularly to Figures 1, 2 and 3, it will be noted that in carrying out my invention, I provide a rear driving wheel 9, and a forward driving wheel 10, running upon one rail, with a third wheel 11 and a fourth wheel 12 running upon the other rail, said wheels 11 and 12 being mounted on the ends of connecting bars 13 and 14C which are held in position by means of the diagonal brace 15 and distance rod 16, and secured as shown to the main frame.

The main frame of the car consists primarily of upper and lower longitudinal members 17 18 and 19, 20 respectively.

As is most clearly to be seen in Figures 1 and 8, the frame members 17 18, 19 and 20 are formed of metallic tubing, preferably square in cross section to better resist the stresses and shocks of service and to afford a more convenient seat for anchorage of the X-form struts and spacing members 21 (Figure 1) and 22 (Figure 3) respectively, whereby the several members 17, 18, 19 and 20 are respectively maintained in proper juxtaposition relatively to each other.

Between the longitudinal members 17, 19 and 18, 20 are mounted the driving wheels and the driving motor 23 secured as shown between the hand lever 2K14 and the forward driving wheel, and having a chain 25 running from a pinion 26 on the motor shaft to a large sprocket ring 27 supported from the axle of the forward driving wheel in a manner to be below described.

At the rear of the hand lever 20 is arranged the operators seat 28, and back of this an extension 29 within which may be located the oil supply reservoir, battery cells, tools and other incidental devices useful in the operation of the car.

'Io provide means whereby two or more additional passengers may be carried at the forward end of the car, I arrange forwardly of the engine and transversely of the framing an extended seat 30 with a suitable foot- Y Y reist V3l by whichvthe passengers are enabledV to face forwardly as is useful in track mspection tours and for other purposes known to railway maintenance of'v way and signal men, Y

The' rear driving wheel 9 is arranged to be Vmanually driven in amanner in all substan- Atial respects the sameas -that described in Y Letters Patent of the United States No.

914,845 granted to me uponthe ninth day of March A. D., 19,09.

.Referring now more particularly to .Figl j ures 41and 5, itwill be observed `that to pro- Vvide -improved means .which will compensate for jars or'shocks; and save the chain Y .fromV thebreakage which I 'have found inthespider 32fwhich isbolted directly to the hub 33 ofV the `forward driving wheel 9 .mounted on the axle 34gv Thespider 32 is provided Vwith an angular, annular groove 35 wherein Imounta ring 36, preferablyof phosphor bronze and substantially 'square cross section, providing the sprocket 27 with 32.V Tol Ythei'end that the tension betweenV asimilar angular annular groove 38 designed Vto receive the diagonally oppositehportio'n of saidring '36. Tohold the sprocket, ring and spider in proper juxtaposition, I provide a Vclamping ring 39, preferably of bronze and having an internal Yslgioulder'40 adapted to fit'cclosely .as a collar a corresponding peripheral .shoulder 41 formed upon the spider Y, the "several members maybe varied as the circumstances of service Vmay require, and in order. to allow VforV compensation Vfor any wear, Ysprings42-Y are interposed between the Vspider and the nuts 43 `sci ewr-threaded upon the studs 44'by means of which the? clamping ring 39 is drawn toward the spider'32.

FromV an inspection of the construction abovedescribed, it VwillbeV perceived that in carrying out my invention, I haveprovided a kdevice which willpermit a certain amount ofV yieldingly resisted slip to occur between' the sprocket 27 and the wheel 9 atthe in- Ystantthe explosion takes'place in the motor,

whereby the chain isV relieved of'eXtraordinary shock, and, as I have found in practice,

Y- Y vbreakage of the chain is avoided.

Referring nowmore particularly to VFigure 6, it will Vbe observed that inthe modified ,form of my invention here illustrated,

YL the hand lever V24 andthe parts actuated c, thereby for driving the rear 'wheel 9 are eliminated. Y ThisV construction permits the Vremoval of the Vseat 2S (Fig. l), the use ofa vertical engine, and thence the, attainment 'i i ofiajfmachine'of'considerably shorter wheel baseand'aione which is more. compactly 'ari Yranged and of stiifer frame. It also allows the seats 29ar 30a to bebrought .closely together and the use of a single running board 31'1 arranged longitudinally of thecar and available to both seats instead of transversely of the car and available only to seat 30a.

i Itl will be understood that as the terms railwaytrack car and veloci ede are used herein, they are used in then' generic sense, and Ythat certain features of construction are not limited to use in a vehicle employing foot .or vmanual driving means or otherwise.

Having thus described my invention and illustrated itsuse, what I claim asnew and desire to securebyiLetters Patent is the following: Y
